OBJECTIVE To determine the usefulness of echocardiography in the diagnosis of heartworm disease in cats and to compare this modality with other tests. DESIGN Retrospective study. ANIMALS 43 cats with heartworm infection that had echocardiographic examinations at 2 veterinary teaching hospitals between 1985 and 1997. Twenty-two of these 43 cats also underwent radiography of the thorax and he...

We calculate the most general effective potential for the massless Thirring model in dependence on all local fields of collective fermion–antifermion excitations. We analyse the minima of this potential describing different vacua of the quantum system. We confirm the existence of the absolute minimum found in EPJC 20, 723 (2001) corresponding to a chirally broken phase of the massless Thirring ...

Groundwater provides the largest source of usable water storage in Bangladesh. samples have been analyzed for Fe, Mn, Zn, Ni, Cr, Cu, Cd, Pb, and Co using atomic absorption spectrophotometer to evaluate heavy metal distribution contamination level at southeastern coastal area Heavy metals are range Fe (490–4710 µg/L), Mn (13–1970 Zn (70–550 Ni (42–255 Cr (25–133 Cu (34–95 Cd (7–26 Pb (0–20 (43–...
